Key Highlights

  • Share price decline: The complaint alleges that on September 22, 2026, Endava's American Depositary Shares fell $0.68 per share, or 24.37%, to close at $2.11 per share on unusually heavy trading volume.
  • Lead plaintiff deadline: Investors wishing to seek appointment as lead plaintiff must move the court no later than November 30, 2026.
  • Delayed financial results: The complaint alleges the company would delay the release of its fourth quarter and full year 2026 financial results because of the accounting review.

Accounting Concerns at Endava Prompt Class Action and Internal Investigation

According to the announcement from Robbins LLP, a class action complaint has been filed against Endava plc, a technology services company operating in North America, Europe, the United Kingdom, and internationally. The complaint alleges that during the class period, defendants failed to disclose that the accounting treatment for certain customer and supplier agreements and related matters required additional review, and that because of this, the company would delay its fourth quarter and full year 2026 financial results.

The complaint further alleges that "there was reason to doubt the effectiveness of the Company's internal controls and procedures" and that defendants' "positive statements about the Company's business, operations, and prospects were materially misleading and/or lacked a reasonable basis." These are allegations made by the plaintiff, not findings of a court. On September 21, 2026, after market close, Endava disclosed that CFO Mark Thurston was placed on administrative leave pending the conclusion of the independent investigation. The firm states that on September 22, 2026, shares closed at $2.11 per ADS on unusually heavy trading volume.

Robbins LLP, which describes itself as representing investors on a contingency fee basis with no upfront or out-of-pocket fees, is soliciting investors who suffered losses during the class period to contact the firm before the November 30, 2026, lead plaintiff deadline. The firm states it has "helped restore more than $2 billion in value to shareholders," though it notes that "past results do not guarantee a similar outcome."

What Was Disclosed

Robbins LLP disclosed the filing of a securities class action against Endava plc, citing allegations related to accounting treatment of customer and supplier agreements, the placement of CFO Mark Thurston on administrative leave, an ongoing audit committee investigation, and a reported 24.37% single-day drop in Endava's ADS price.
